Abstract (en)
[origin: EP3708943A1] To provide a friction reduction device to reduce fri ction between a piston and a cylinder. A friction reductio n device to reduce friction between a piston and a cylinde r has a piston into which a gas flows and that retracts in order to load the next bullet, a cylinder that accommodat es the piston so same can move, and a piston rolling body that is rotatably disposed in the piston. The piston rolli ng body is rotated by the piston rolling body rotatably di sposed in the piston being in contact with the interior of the cylinder when the piston is retracting.
